摘要: | 在本论文中,主要提出了一种新的参数控制机制:``EWMA-II''。它弥补了 漏桶 (Leaky Bucket; LB) 用者不佳的监测能力。EWMA-II 机制的主要功 能 均丛聚长度。同时,若使用者因平均丛聚长度增加导致平均封包率上升 时,EWMA-II 机制亦将会获得一个较 LB甈陛C它的效能分析我们将从数值 方法及计算机模拟两方面来探讨。 EWMA-IID常简单,因此若EWMA-II 机 制与两级的 LB责最大封包率的监测,另一级负责 □,我们将可获得一个完 整的参数控制机制的架构,足以监测任何语音封包的使用者。 □探讨了预 支型参数控制机制的效能,包括``预支型滑动视窗机制'' 窗机制''及``保 留-预支型跳跃视窗机制''。同时我们亦探讨了非法使用 的变化种类,并 逐一对LB机制及指数加权移动平均(Exponentially Average; EWMA) 机制 做测试,最后我们对Turner 先生[15]所提出的 W宽配置法则及使用参数控 制做了修改,使其更符合实际系统的执行。 In this thesis we propose a new policing mechanism called EWMA- II compensates the policing capability of Leaky Bucket scheme topliant sources for which the peak rate and mean rate are compliant whilelength is over contract. The main feature of EWMA-II is to police the of a source. Also, when the mean rate of a non-compliant source increases due to the increase of its mean the EWMA-II policing scheme can achieve a very good static behavior and a fast dynamic behavior. The performance of EWMA-II mechanism is studied by numerical simulation results. The hardware implementation of EWMA-II is Hence, if EWMA-II is cascaded with two stages of Leaky Bucket (one policing peak rate, the other policing mean rate), we any type of non- compliant on-off sources to prevent network In the rest of this thesis, we study some other new policing including ``Preuse Moving Window''(PMW)、``Preuse Jumpingnd ``Reserve Preuse Jumping Window''(RPJW). Also we classify the non-compliant sources, and test the performance of LB and EWMA by these sources to both mechanisms. Finally, we modify theation algorithm and usage parameter control mechanism for data packets Turner[15] to make it practical for real systems. |
